To 0Z5 whom may concern:

Be it known that 1 Leo Bloom. a citizen of the United States, residing at New York city. borough of Brooklyn, in the county of Kings. and State of New York, have invented a ce'tain and useful Combined Burner and Heater. of which the following? is a specification.

This invention is a gas burner and heater and is adapted to be mounted on ture in the position usually occupied. by the conventional burner tip and utilized for ligitiun, heating or cooking purposes.

The obiect of the invention is to provide it device of simple construction. one which may be sold at hardware or fixture stores and installed by the purchaser in a simple and efficient manner, thereafter to be used. for the purposes specified.

A further object of the invention is to so construct the device that the lighting elenients thereof may be controlled independently oi": the heating and cooking elements thereof.

it has heretofore been suggested to control the How of gas to both the lighting and cooking elements by means oi? a single cock, which. when in one position, supplies the one to the lighting burner and sluits off the gas from the cooking; burner and when. in another position. supnlics the gas vice versa. Finch coclr has further been made so as permit of the operation of both lighting and cooking burners at the some time. but with such devices it extremely dil'hcult to know before turni the handle of the burner cool: What is go to happen, and. not infrequently. the cock operated ininr wi'l i to .1urn oi'f from the but which it is desired to con-- tinue in operation and su iipiy to the burner which it is desired to rem: in inoperative.

accm'dan 'e with the present invention. person can tell at a glance how to oper ate the device since each burner iscontrolled by a separate cock, operating in a well known onventional way.

Another feature of this invention is the incorporation in the device, in conjunction with the cooking burner. or" a heating plate which may be heated by the cooking burner and is adapted in turn to radiate it heat for the purpose of heating a r0.

Features of the invention other than those specified, Will be apparent from the heroin after detailed description and claims. when read in conjunction with the accompan vi. drawings.

The accompanying drawings illustrate one practical embodiment of the invention. but the construction therein shown is to be understood as illustrative. only, and not as defining" the limits of the invention.

Figure 1 is a side elevation of device embodying the present invention: and.

Fig. 2 is a perspective view of tho coclc ingburner of said d vice showing a heat attachment which .l employ in central tion and in dotted lines.

Referringto the drawings. designates a conventional 'a-s llXilUl'E. such coin-- inonly installed in building's and dwellii This fixture is provided at its outer With an elbow (I provided with an upsta ing threaded portion 0, adopted. to the usual burner tip {or ilhnninatineourposes.

The device of the present invention embodies a body portion preferably in the form 03" a casting, torniino a union. The castingis pro. pending shank 7) which is inrerio ed to snow on to the threaded nor of the elbow a and has two upst threaded. nipples b and 6 The is cored or made hollow so T be s1. plied "from the fixture A. one of the threaded nipples h and 71 Screwed upon the threaded nipple Z is a plug cock E provided with the us piece a. While on the F provided With a inner the operations 0'? the lin the supply of gas ma be r trolled.

Screwed on to the plug cock is :i. bu coca tip C of the kind coinnionl employed in! lighting purposes While screwed on to the cool: F is a Bunsen tube the upper cud of which carries a heating burner The heating burner G embodies an annular plate 9 supported by radial arms 9 and issuing from holes 9 in the burner is ignited exteriorly of said holes and the flames coil up through the annular plate for the purpose of heating the receptacle supported on said plate.

oi the? end ll and coil.

The burner tip C and cooking burner Gr are preferably so related in position that it flame is burning at either, the turning on of the other will result in ignition of the gas at the burner last turned on.

it is desired to use the device for illuminating purposes only, the plug coclr F will be turned oil and the plug cock E turned on and gas ignited at the tip C. 11' it is now desired to cook on the plate g, it is only necessary to turn on the plug cock F, whereupon the gas will. immediately ignite at the burner G and cooking may be carried on. 91" course it will be understood that the burner may be operated to the exclusion of the illuminating tip C, that, in tact, either may be used without the other or both may be used together through proper manipulation of the cocks and F.

In order that the device may be eiliciently employed to heat a room, radiating meniber H is pro *ided which may vary inform, but is shown in the drawings as consisting of a sheet metal plate. This plate is provider at its center with a depending portion it which may be formed by stamping down the center of the plate or by mounting a separate member thereon and this depending portion, which in either event, is in the term of a boss, is adapted to occupy a position between the inner ends or the radial arms g when the radiating plate is laid upon the cooking plate 9 after the manner shown in Fig. 2. The boss it will centralize the radiating plate with reference to the burner and preclude said plate from inadvertent dislodgment, although the plate may be readily lifted oil in the event it is desired to employ the burner g for cooking purposes.

When'the radiating plate H is employed, it will manifestly become highly heated when gas is ignited at the burner G and will serve to radiate its heat throughout the rooinfor the purpose of raising the temperature of the room.

it will be manifest -from the foregoing de 7 tailed description of the invention that the device is extremely simple andyet highly eiiicient in they carrying out of its intended functions. No skill whatsoever is required to manipulate or operate the same, and, being very compact, it is particularly adapted for use in the sick room or in the nursery where food or heat applications are required from time to time especially at night. The present invention is not, however, restricted to thesespecific uses, but is adapted for broad application.

The device may be economically manufactured and embodies several stock fittings,

which ma be bou ht in the oven market and each casing having a male threaded portion at its top, a separately and independently operable plug valve in each casing for controlling the flow of gas therethrough, an upstanding burner tip screwed onto the male threaded portionsot one valve casing, an upstanding Bunsen tube screwed onto the male threaded portion of the other valve casing; and extending upwardly beyond the top of the burner tip, a cooking burner mounted on the top of the Bunsen tube, and a pan supporting grid mounted on the cooking burner. a

2. A device of the class described embodying an intergral three way T-shaped union, the horizontal portion of which-is formed, intermediate its ends, with a depending interiorly threaded leg adapted to screw onto a gas fixture and the opposite ends of which portion are formed with upstandin parallel, exteriorly threaded arms, an upstanding plug-valve casing screwed onto each arm and each casing having a male threaded portion its top, a separately and independently operable plug valve in each casing for controlling the flow 0t therethrough, an upstanding burner tip screwed onto'the male threaded portions or one valve casing, an upstanding Bunsen tube screwed onto the male threaded portion of the other valve casino and extending upwardly beyond the top or the burner tip, a cooking burner mounted on the top of the Bunsen tube, and a pan supporting grid mounted on the cooking burner, in combination with a radiating plate of larger dimensions than the grid andprovided at its center with a depending portion adapted to interfit with the grid to demountably maintain the plate in centralized portion wherein it will overlie both:

the'cooking burner and the burner tip, the latter of which may be used to produce a simmering flame.

In testimony whereof, I have signed my name to this specification.
